I don't think solder on traces helps. That is not an issue. Issue would be mosfets ratings, their temperature when working at high current, heat dissipation. Thick traces would be overkill. Adding small fan or heatpipes would help with the heating.

Thank you for deciding to clean the thermal compound in the last second

given the amount of effort I would have laid some de-soldering braid or thick wire down just to add some copper to the mix

Cool stuff really useful to get tried and tested advice on the settings. I have 3 controllers in a box somewhere, I'm gonna give this a shot see if I have the beefy traces too. My m365 is a 1s running the pro custom firmware, so I'm guessing it doesn't have the traces beefed up. There's a nice guide on scooterhacking's wiki on swapping mosfets and caps to support higher battery voltage (12s basically), might try that for next summer.

I actually got my original controller (which was the best one i recon) burned up from over-use as it broke originally. That's not just my bad, but what i ordered was lied about and i never got a new original pro2 controller. I did however charge my pro2 up to the max from nothing and went for a ride down-hill. Breaking at certain sections fryed the rails. I could then see that reinforcing it could have saved me that time. But i am afraid it wouldn't matter anyways since it can happen again if the scooter is too hot, max battery, and you break a lot down-hill right after you hit max charge. I still did repair my older controller, i got 3 but 2 works and my original is dead. If the controllers are lacking anything in my opinion, it has got to be cooling solutions with how horribly hot they tend to get randomly.

I was thinking of doing this with my Aovo 365(clone) but they encapsulated the whole board:( -You would think 0n this that they'd screw the FETs down and use a blob of Angel sh*t (heat transfer compound) on the thermal feedback at least wouldn't you? It might be worth trying, you might get a few more Amp out of it yet-just make sure you use screw insulators when screwing down the fets,TBH the heatsink looks a bit pap-I'd be tempted at something like a CPU cooler or even 3 little ones-1 for each phase, I'm going to see if I can get some Xiaomi esc's-I've got extra battery, Motor and an urge for a fast 2wd :) . All the best.

nice, thanks sir

extra chunky solder wont help much there. clean it off put copperbusbar that go the length and goes to fets and pwr (coppersheet cutout the shape and solder it to controller and u never gonna blow the traces

You should get a spade or a knife tip for this sort of work that tip isn't ideal and maybe also look into upgrading those MOSFETs just make sure the controller doesn't use the MOSFET's Rds on for sensing. current.

I have an M365, and I did the same thing, not quite as thick with the solder, but I added some bus bars. Then I added another battery in parallel, and my wife scooter is the exact same thing, but no mods completely stock controller stock battery. all I did was change the firmware on the battery and put custom firmware on the controller. the same exact firmware that I'm using, and hers is faster. Lol, the only difference between the two scooters is hers has stock tires and I have 10 inch tires. It has to be the tires. I'm happy with the speed overall. I don't think there's really a need to go much faster. it'll do 29kph. But I weigh 200 lb, and I want a little more power to go uphill. I'm thinking about reinforcing my controller to go to 72v but just limiting the amperage to like 25ish amps.... according to what I've read 35 is about the Max. But even if I run 72 volt at 18 amps its still twice the wattage.

Hi was there much of a power upgrade' how did it go ?

My 1s is with stock Controller at 1,23 kw Output.and it works fine.

Use some good thermal pads under the mosfetsi used gelid extreme they were around 12-15 euros but 17/Wmk and some good quality paste under the controller i saw 30+c difference controller stopped overheating even at 1kw.

The traces on my mosfets were with much less solder. I fluxed in much more just to reinforce them but I'm still afraid to flash it and boost the speed. It's my daily to work, 7 km trip each way. I have 700 km on the clock

where is the f2 fuse in this board please ?

Hi i got the same scooter as you have, just have 35 km/h mod done. But struggles uphill, do you recommend doing this mod ?

As you were mentioning the 35 amps uphill in 2 people, did you do it before the controller reinforcement or after? I am running 30 amps right now in a hilly area and its too weak so i am considering to juice it up a little more. Thanks and have a wonderful day.

Hola,Hola que tal La soldadura de estaño de plata seria mejor o simplemente estaño normal

Hello, I wanted to ask you 2 questions, the first is what those 100 volt MOSFETs are called, and the second is, can the control unit without modifications of the pro 2 handle 58 volts without causing damage?

What kind of mods or to change on v3 controller to handle high volt battery?

<a href="#" class="seekto" data-time="628">10:28</a> Is that yellow tape kapton tape? You really need to remove that as that is a insulating tape and will totally ruin the thermal conductivity for the mosfets.

Can you help me. How to remove DRV VER SPOOFING:555 on my mi scooter 3. Because i cannot put an external battery for the reason that i cant disable charging mode no matter i custom firmware. 😢. Hope you notice me. Thanks in advance.

My scooter cuts out when riding do you know how to fix this I’ve tired lowering the amps tried New batteries and still hasn’t worked plz help

i have an issue that is when i turn on headlight , the dashboard is off and motor become slower and headlight is low .. how can i repaire it please ?

Why the hell did you put Thermal pad on the back of controler. New thermal paste is the right solution like on computer CPU. You won't EVER see pads there. Youcan put 1 mm thermal tape under mosets ( but remove original yellow tape from there (it has worse thermal conductivity than thermal pad)

doesnt work for my scooter 3…firmware is new

Funny thing I went to a guy today who fixes electric scooters so he can downgrade my ble version , he said that he leaves the max draw at 900W for pro 2 and 800W for 1s etc... Without reinforcing.I thought it was too much especialy since I live in greece but it seemed like he has been doing that for some time to xiaomi scooters.I changed it mine ofcourse when I came back in my house since I've been reading that 30A is the maximum.

My brake max break amp is 55 is it dangerous? Standard I have 31 in sports mode with reininforcing the BMS

How do I make my own firmware for more voltage??

hey mate,do you know where i can buy an external battery?

Why don’t you touch on the maximum limits? 60A is safe?

I just put 350w on mi xiaomi s1 should i do this on my controller ?

Can I buy this moderboard and change it on my M365 Pro?? (I mean the normal one, not the v2)

This wil work in a xiaomi 1S? i've been told that the motor controller it's the same.

is it possible for the cables to overheat and melt withs this firmware?

So what’s your new top speed ? 😅

So it's just useless, go tu buy à dualtron mini 1000W 1450 peak and same price as Xiaomi pro 2 + mods

Why not just take nickel on top?
